To (all whom Ps1/tj concern/,-

Be it known. that il, JULIAN KENNEDY, oi Pittsburg, A llegheny county, Pennsjvlvenie, have invented :i new and i feiul '.ltolling-lt'lill, oi' which. the following is e `lull, eleer, and ex eet deseiiption, ielerenee being lied 'to the iteoompanying drawings, foi-ming pei-t oi this speeiiieation, in which# Figure is a side elevation, partly in seetion, of einiiveisnl inill constructed in accordenoe with my invention. Fig. 2 is e. front eleve-tion oi the mill viewed fiom the right ol Fig. l, the gear-easing et thelowei part of the tlg-nie being in vertieei section. 4, and 5 show e modification in which the pinione ere the upper end oi" the mill. Eid. J5 is e front elevation, the geenoaeing being shown in veitienl seetion. Fig. on end elovnftioi'i viewed from the riglithend side oi' l* .5, ports of t 'no opp eretns being shown in retti-eel si ion, Fig. 5 is en .teguler hoiizontel section on the line wi7 V of Fig. 3, and Fig'. 3a is a. diegi'emni ntie view.

Universel mills es hei'etoioi'e constructed lieve been objectionable in Arespect ot the oomW plioetion of their gearing, which have been constructed so es to ti'evel with the vertioal rolls in their .lateral adjustment, nini it is for the 'purpose of overcoming the difficulties inevident to suon constructions that fl have de Vinod my invention, which consist-s in the eoinhinetion oi leLemlly-moveble vertical trolls inminte-i with in the housings of the lioii- L/.ontel rolls end pinionnr mounted in stationary bearings above oi' holow the rolls end connected therewith by niovehle newer eeniieotion, so that the Toile een he adjusted to and from eachother with-ont moving the pinions. This greatly simplifies the eppeintns :ind iuovn null which is eesy to Keep in repair end easy to liihiieete. it enables me .ien-nwe the pinions from difeot eonnection to the rolls nifl to inolose them, tlins ohvieting the trouble wliieh has been oxpiarienoet in keeping in order the exposed laterally movin `pinions heretoioie employed.

l have shown in the drawings two foinis of my invention which i regard es 1ei"eal. le; but those skilled in the mfr, will be a-ble to modify it further to snit the particular uses to which it is to he put.

Yin Figs. l. end 2, :2 represents the housing of e. universel mill. 3 3 are the liorizoi'ititl rolls, and 4 designates the usuei leed-rollers.

The veitienl rolls 5 5, to which my invention pnitieuieily i'eletos, are gourneieo 1noeeiings o C7 et their lower end upper ends. These beatings mounted in vertical let erellyqnovfible frames or housings 55, which ere'set within the housings oi' the horizont-el iolls upon horizontal slide-hers 9 and l0, mound which and within the frames l may set bushings l i, by which the friction of sliding is ieduoed. As the vertical tolls are eet Within the housings of the horizontal rolls, the `mill is rendered very compnet and its ef- 'lieienoy and strength is glee-tlv increased. Each of the frames S is prefeiebly inede in two divided sections held together by loolts le, so that they may be iitted around the necks of the veitieel tolls. At the lower end of eeeh of the veitieel iolls'is a. Webblei eon neetionl 5, coupled flexibly with a spindle 16, the connection shown in Figs. l e 2 Vbeing the Seme es that for which Letteis iletent No. 566,144 were granted to me on January 15, i901; hut otlie suitable ivebhlei connections .may he employed, the 'outpose being to pro vide universal jointe between spindles and lower end of the rolls. The .spindles are connected et theii` lower ends oy e similar universel joint l? to the vertical shafts H3 of the pinions i9 and 20. 'ihese two pinions are inoesed in stationery piniondiot 2i, in which' they ere mounted in vei enl heat-- ings, and ere geared togethei. "i ne pinion Ois connected to or mede integral with e `beveled gear L2, driven oy a beveled pinion 23 on e horizont l shaft 2e. The pinions are covered. and shielded by can 25 end the housing may he charged with oil, so to immerse the pinione eine. to keep ti. e perfectly lnbiioetetl.

At the hase of oooh Aninio step 26, which is vettioelly e the slieiit by Wer7 screw Whioli ont nels t pinion-housing and lies n. i Wliiol'i it may ive tnined eo es to nieve the Wedgeoint 27 in oonteot with inclined block 29 et its end thus to edjnst it vel"- tioall'yl The pit 30, in, which the pinion-housing is set, may be coveted with a. hood. 31 to exclude seele, end the nehmer-joints 16 und 17 may he surrounded by e jointed and flexible ossing formed oll inte. {ii/ted parte 32 2%: The top openings o? the hood tonnil the Web- Mer-shaft ne formed by turret-like projections Sfi of sulieient to :111mgv the necessa @salse spindle.

rlhe facility which my invention al'l'ords f for incasing and protectingl the gearing is of "great practical importance. l In the` use of my apparatus the vertical rolls are"driven by power transmitcd from the shaft 24 to the gearing 23, 22, 21'), and 19, to the spindles 16, and thence to it rolls, which will be driven thereby in cv position of' their lateral adjustment, which is el"- fected by adjusting mechanism applied to the frames 8 and operated by hand or by suitable motors. For this purposel I may use the a(.lju.stingscrews and gearing 36, (shown in F 27,) or I may substitute thorelor suitable hydraulic cylinders, the purpose being to move thc frames 8 laterally on the slides 9 10, and thus to move the rolls toward and. from each other. rlhis motion is permitted by the spindles and their llexi ble connections 15 and 17. Each vertical roll is preferably support ed at its upper end by a collar 412', resting upon an annular bearing 13, having a spherical contour and resting in a spherical cavity on the frame 8, so that by sclli-adjusti'nent of this universal bearing an even pressure is obtained on the rubbing-surfaces which support the rolls; A ring of vulcanized -i'iber or other suitable antifriction material 44 is preferably interposed between these rubbing-surliaces- For the purpose ol lubricating the rolls and the pinions I preferably employ the device illustrated in Fig. 1. Each vertical roll has an oil-passage 37 extending through it from.

top to bottom and having lateral passages 38, leading to the uppery and lower roll bearings. Below each of the passages 38 the central passage 37 is plugged, at 38', so as to cause the oil to pass out through the passage 38 to the necks of the rolls. Below the upper neck of the rolls is a return-passage 38', leads the oil from the bearing transversely through the body of the roll and back to the passage 37, whence it passes to the bearing of the lower neckand thence into the casing 32, surrounding the coupling 15, whence alter iilling the cavity of' the coupling to the level ol" a central passage 40 it Hows therethrough into thelspindle. The oil-passage in which the spindle leads to the coupling 17, where after forming a pool ol'" predetermined depth the oil passes through a passage 38b to the upper end of the bearing of the pinion-shaft 18 and passes thence down into the pool of oil contained intrie pinion-housing. Thus by supplying oil to the upper part of the verti pass in series to the sev cal rolls ,l cause it y l eral roll-bearings, ie spindle connections,

l and the pini oil-bearings without need of separately supplying lubricant thereto.

in the modifications shown in Figs. 3, 4g, and 5 the arrangement of the mill is reversed, the stati onarylgiearings 'for the pinions being at the top of the roll-housing instead ol the bottom, shown in Figs. 1 and 2. In these 'figures l show two pairs of vertical rolls 5 5 and 5"' 5a on opposite sides, oi' the lifiirizontai rolls, their driving-pinions being own in diagram in Fig. 3a. A central driving-pin ion B is in gear with the pinions C 'of two of the vertical rolls on opposite sides of the' horizontal rolls, and these in turn drive the pinions E F of the other two vertical rolls. All these pinions are inclosed in the casing G at the upper end of the roll-housings and are connected with the vertical rolls by spindles 16 and flexible connections or wabblers 15.

I claim- 1. In a rollingmill, a vertical roll having a vertical oil-passage therein, driving-pinion 'for said roll, a drivingspindle 'universally jointed `to the roll at one end and to the pinion at the opposite end, and also having an eilpassage therethrough, and casings surround ing the universal joints or couplings and having communication with the oilpassages in the roll and spindle; substantially as deM scribed.

2. In combinations/*ith vertical rolls and driving-pinions below the same, a hood having turret-like projections ci suiiicient size to allow the lateral motion of the spindles, and. a second hood on the spindle overlapping said projections; substantially as descriiiied.

In testimony whereof I have hereunto set my hand.
